You can choose from all our ranges of up-and-over and sectional doors.

The purchaser of a Spadone garage door benefits from a 10-year warranty starting from the date of purchase, ensuring reliable and secure operation of their garage door under normal conditions of use and installation.
The original model reference is engraved on the upper pulley bracket or on the lower spring bracket.
This set of springs and hooks can replace the following original spring references on Hörmann, Tubauto Ecostar, or AGS garage doors:
- Tension spring 751
- Tension spring 752 - Sectional Door AGS
- Tension spring 753
- Tension spring 754 - Sectional Door Hörmann Z fitting
- Tension spring 755
- Tension spring 756
- Tension spring 757
Our tension springs are equipped with a hook loop at each end. The double-groove pulley delivered with each set has a perforation for the upper hook of these springs. A lower hook with a perforation and 2 screws is provided to replace the original lower fastening.
On Hörmann, Tubauto, and AGS doors, you have the option to adjust the height of the hook notch at the bottom of the door to pull more or less on the spring and fine-tune the power to correctly balance your garage door.
To safely change your spring, lock your garage door in the open position using a clamp. This way, your springs will not be under tension for disassembly.
Maximum tension: we recommend not stretching the spring beyond 2.5 times its length at rest to preserve its normal lifespan, which is 180cm in extension with the door in the closed position.
Whenever possible, replace garage door springs in pairs. This ensures equal balancing force on both sides of your Hörmann / Tubauto sectional door. Additionally, if one of your door's springs is broken, it generally means that the spring on the opposite side is likely to break in the near future as well.
